(Cl. 53-24) This application is acontinuation-in-part of my copending application Ser. No. 232,463 filedOct. 23, 1963 and now Patent No. 3,262,631.

This invention relates to a process, container and apparatus forconfining yieldable material and is more particularly concerned with afibre board container, an apparatus for compressing the container andthe process of packaging compressible material in a compressed conditionwithin the fibre board container.

In the past it has been common practice for cones of synthetic yarns tobe packaged in side-by-side relationship in layers separated by fibreboard dividers, the dividers having spaced holes through which the endsof the spools project. Since a large quantity of yarn is packed in asingle container, the container has usually been provided with an accessdoor for closing a side opening, the packer thereby having accessthrough the opening to a depth in the container in excess of his normalreach. These containers must be closed under compression whereby anytendency of the yarn to shift within the container is 1 eliminated.

Heretofore, the compressible containers generally used were all twopiece containers having a body and a cap, the cap telescoping onto thebody and being urged by a ram against the upper edge of the body so asto compact or compress spools of yarn into the dividers as a metal strapor straps were passed around the container to retain the cap in itsseated condition.

The two piece prior art containers, while holding the yarn firmly inplace for shipping, are bulky, expensive and require considerable floorspace for packing. Hence, the trade has long sought a one piece fibreboard container which may be packed under compression.

Heretofore, it has been believed that it was impossible to pack a onepiece fibre board container under compression since, in so doing the topflaps must be progressively closed over the protruding top of the yarns,thereby breaking the top flaps and causing them to roll around thisprotruded material.

Contrary to prior art beliefs and practices, I have devised a one piececontainer and a method of packing the container whereby, the flapsforming the top are closed over the top of the compressible materialwithin the container, prior to compression and, thereafter, the top isurged downwardly to a seated position adjacent the top edges of thepanels. Then, the top is locked in its seated position, holding thecompressible material in a compressed condition. For this purpose, thetop flaps are respectively joined to the upper edges of the panels,which define the tubular portion of the container, through toggle-likecomplementary intermediate flaps which initially space the top flapsfrom the top edge of the panels. The intermediate flaps have theability, however, to be jack knifed outwardly as the top flaps, in theirclosed conditions, are urged toward the edges of the panels. As the topis seated on the upper edges of the panels, the intermediate flaps arebrought into horizontal juxtaposition with each other and the top flapscore lines are brought into coincidence respectively with the panelscore lines whereby the intermediate flaps may be folded, along thecoincident score lines, to vertical positions against the outer surfacesof the upper portions of the panels. Next, a strap or other arrestingmember is passed around the intermediate flaps to secure theintermediate flaps in posi- 3,345,796 Patented Oct. 10, 1967 tion sothat they, in turn, hold the top i.e. top flaps seated in positioncompressing the yarns within the container.

The present invention also includes a ram mechanism having a platen bywhich the top flaps, after forming the top, are urged toward the paneledges and pivoted fingers which move in arcuate paths inwardly so assimultaneously to urge all intermediate flaps from their horizontalpositions to essentially vertical positions respectively abutting theouter surfaces, of the panels. The fingers are sufiiciently flat andoccupy little space outwardly of the intermediate flaps to permit theinstallation of the compression strap thereabout for retaining theintermediate flaps and therefore may be withdrawn as the strap remainsaround the intermediate flaps.

Accordingly, it is an object of the present invention to provide aprocess by which compressible material may be quickly, easily,inexpensively and efiiciently packaged in a compressed condition withina container.

Another object of the present invention is to provide a new use for aone piece slotted box.

Another object of the present invention is to provide an automatic ramwhich is particularly suited for compressing a one piece containerhaving intermediate flaps.

Another object of the present invention is to provide a strong,inexpensive, one piece container which is capable of receivingcompressible material, of being quickly and easily compressed whilecontaining the material and of being secured for retaining thecompressible material in its compressed condition.

Another object of the present invention is to provide a container whichis suitable for forming either a relatively short or a relatively longcontainer.

Referring now in detail to the embodiment chosen for the purpose ofillustrating the present invention, it being understod that in itsbroader aspects, the present invention is not limited to the exactdetails herein depicted, numeral 11 denotes generally the container ofthe present invention which is essentially identical to the containerdisclosed in FIGS. 1 through 4 of my copending application Ser. No.232,463 filed Oct. 23, 1962, except that, in the present embodiment,intermediate flaps are provided between the panels and the top flaps, aswill be described hereinafter.

The container 11 is formed from a fiat rectangular blank of fibre boardscored to define four side panels, namely panels 20, 21, 22 and 23. Morespecifically, the numerals and 21 denote the opposed side panels of thecontainer 11 while the numeral 22 denotes the front panel and numeral 23denotes the rear panel.

The panels are initially in side-by-side relationship, the panels 28 and22 being joined by a common edge or score line 24, the panels 22 and 21being joined by a common score line 25 and the panels 21 and 23 beingjoined by a common score line 26. One of the outer panels 21) or 23,such as panel 23, is provided with the usual flange 27 on its outeredge, the flange 27, and panel 23 being joined on a common score line28. When the container 11 is squared and the bottom flaps, such as flapsand 47, closed in the usual way to form the bottom, the score lines 24,25, 26 and 28 form the vertical edges of the container 11.

The panels 20, 21, 22 and 23 are each rectangular members providedrespectively with top flap members. The top flap members extend from theupper edges of the panels 20, 21, 22 and 23. Specifically, panel 20 isprovided with top flap member 29, panel 21 is provided with top flapmember 31, panel 22 is provided with top flap member 33 and panel 23 isprovided with top flap member 35.

The top flap members 29, 31, 33 and 35 are separated from theirrespective panels by horizontal or transverse panel score lines or foldlines 40, 41, 42 and 43, respectively.

As best seen in FIG. 1, an access door is formed in the front panel 22.This access door 50 is defined by a pair of straight parallel, verticalor longitudinal cuts which are spaced inwardly from and parallel to thescore lines 24 and 25. The upper ends of these vertical cuts intersectoutwardly extending cuts on score line 42 while the lower ends of thevertical cuts terminate in the central portion of panel 22. A straighthorizontal transverse score line or fold line 53 joins the lower ends ofthe cuts. Thus the access door 50 is defined by the score lines 42 and53 and side edges 51 and 52, formed by the vertical cuts, these sideedges 51 and 52 being spaced inwardly from and parallel to the scorelines 24 and 25 respectively. The panel 22 now forms a U-shaped fixedpanel which receives the access door 50, the door 50 being inessentially the same plane with the remaining portion of panel 22 whendoor 50 is closed.

Referring now to the top flap members 29, 31, 33 and 35, it will be seenthat each of these is provided with a pair of intermediate flaps and atop flap. In other words, the flap member 29 is provided with a pair ofparallel score lines 54 and 55 which are parallel to the score line 40and to the outer edge 56 of the flap member 29. This divides the flapmember 29 into an inner intermediate flap 57, and outer intermediateflap 58, hingedly secured together along score line 54, and a top flap59 secured to the outer intermediate flap 58 along the top flap scoreline 55. In identical manner, the flap member 31 is provided with a pairof score lines 64 and 65 which separate the flap member 31 into an innerintermediate flap 67, and outer intermediate flap 68, a top flap 69having an outer edge 66. Likewise, the fiap member 33 has score lines 74and 75, inner intermediate flap 77, outer intermediate flap 78, top flap79 and outer edge 76 while flap member 35 has score lines 84 and 85,inner intermediate flap 87, outer intermediate flap 88, top flap 89 andouter edge 86.

It is important, in most embodiments of the present invention, that allintermediate flaps be of approximately equal width. In other words, thepanel score lines 40, 41, 42, and 43 should lie in essentially the samecommon plane when the access door 50 is closed. Furthermore, the commonintermediate flap score lines 54, 64, 74 and 84, when the blank for thecontainer 11 is formed, should be in alignment with each other while theflap score lines 58, 68, 78 and 88 should, likewise, be in alignmentwhen the blank is initially scored. Also, the distance from score line40 and 54, from score line 41 to score line 64, from score line 42 toscore line 74 and from score line 43 to score line 84 should be equal,or approximately equal to the distance from the score line 54 to scoreline 55 which in turn is equal to the distance from score line 64 toscore line 65 and the distance from score line 74 to score line 75 andthe distance from score line 84 to score line 85, thereby assuring thatall of the intermediate panels 57, 58, 67, 68, 77, 78, 87, and 88 are ofequal width. The purpose of providing the equal width intermediate fiapsis that the score lines which are common to both intermediate flaps,namely score lines 54, 64, 74 and 84 should be moved outwardly insynchronization as the inner and outer intermediate flaps hinge togetherin response to movement of the top downwardly, as will be explained morefully hereinafter.

Referring now to FIG. 2 of the drawings, the mechanism for compressingthe container 11 includes a hydraulic ram mechanism having a main pistonrod 90 which is carried, for reciprocation in a vertical path, by apiston (not shown) within a double acting hydraulic cylinder 91 suitablymounted in a vertical position. Any suitable hydraulic fluid may beutilized for actuating the piston (not shown) both in a downwarddirection and in an upward direction to extend and retract the pistonrod 90. Since the operation of hydraulic rams is well known, the detailsthereof are not included in the disclosure, it being sufficient to notethat through hydraulic actuation of appropriate mechanisms (not shown)the piston rod 90 is caused to be retracted or extended, as desired.

On the lower or outer end of the piston rod 90 is a fiat, square orrectangular horizontally disposed, plate or platen 92 which correspondsgenerally to the dimensions of the top of a container, such as container11. The plane of platen 92 is perpendicular to the axis of rod 90.Adjacent the periment-al edges, respectively, of platen 92 are aplurality of upstanding brackets 93 to which are respectively secured aplurality of pillow blocks 94, the pillow blocks along each edge of theplaten 92 being in alignment.

The pillow blocks 94 along one edge of platen 92 journal for rotation ashaft 95 while the pillow blocks 94 along an adjacent edge journal ashaft 96. The pillow blocks 94 along still another edge of platen 92journal the shaft 97 while the pillow blocks 94 along the fourth edgejournal the shaft 98. The shafts 95 and 96 terminate outwardly of thepillow blocks 94, adjacent each other and are provided with beveledgears 100, respectively, the gears meshing so that rotation of shaft 95will cause equal rotation of shaft 96. In like manner, shafts 97 and 98are coupled together for simultaneous rotation.

The shafts 95, 96, 97 and 98 are provided with a plurality of radiallyextending, axially spaced, fingers 101 formed of relatively rigid flatmetal, the fingers 101 extending generally outwardly from theirassociated shafts and terminating in rounded ends 102.

The outer fingers 101 on shaft 95 extend upwardly and inwardly above theshaft 95 and are pivotally connected respectively to the ends of rigidlink members 103 and 104 which extend inwardly over the platen 92 andare, in turn, pivotally connected to the lower ends of levers 105 and106. In like manner the fingers 101 on shaft 97 extend upwardly andinwardly and are pivotally connected to links 107 and 108 respectively,the links 107 and 108, in turn, being pivotally connected to the upperends of levers 105 and 106. The central portion of levers 105 and 106are fixed to the ends of a transverse shaft 110 so as to rotatetogether.

The shaft of 110 is supported by pillow blocks 111 on a T-shaped block112 carried on the upper surface of platen 92. The central portion ofthe T-shaped block 112 supports a hydraulic cylinder 113 which actuatesa piston rod 114, the piston rod 114 being connected pivotally to theouter end of an operating lever 115, the inner end of which is securedto the central portion of shaft 110. Thus, upon actuation of thecylinder 113, the levers 105 and 106 are rotated, or rocked, in aclockwise or counter clockwise direction to thereby rotate by the links103, 104, 107 and 108 the shafts 95 and 97; the shafts 95 and 97 throughthe beveled gears, such as gears 99 and 100, also rotating the shafts 96and 98.

It is now seen that the fingers 101 are controlled by piston rod 114 topivot'simultaneously in arcuate paths from generally outwardly extendingor horizontal positions to generally downwardly extending or verticalpositions when the piston rod 114 is extended. When piston rod 114 isretracted, the fingers 101 are returned from their downwardly extendingpositions to their outwardly extended positions.

The introduction of hydraulic fluid to cylinder 113 on one side of itspiston or the other is controlled by solenoid (not shown) which arerespectively actuated by actuation of limit switches 121 and 123 carriedon a vertical rod 122 adjacent and parallel to piston rod 90. Projectingfrom the central portion of piston rod 90 is a limit switch actuator 120which, when the piston rod 90 approaches its downrnost extendedposition, engages and throws the bottom limit switch 121. In likemanner, the actuator 120 throws an upper limit switch 123 when thepiston rod 90 approaches its most retracted position. The throwing ofbottom limit switch 121 causes cylinder 113 to extend piston rod 114 andthe closing of limit switch 123 causes the cylinder 113 to retractpiston 114. Thus, when the limit switch 121 is actuated, the fingers 101which remain extended generally outwardly, are pivoted to downwardlyextending positions and when limit switch 123 is actuated, the fingers101 are returned to their outwardly extended positions.

Operation From the foregoing description, the operation of the presentinvention should be apparent. When a container, such as container 11 isreceived, it is righted to the condition shown in FIG. 1 and the bottomflaps 45 and 47 are closed in the usual way. Thereafter, the door 50 isopened to permit access to the interior of the container 11.Furthermore, the flap members 29, 31, 33 and 35 are folded generallyoutwardly, along the score lines 40, 41, 42 and 43. In such condition,the packer packs the container 11 with a plurality of cones of yarn 130on spools 132. After each layer of cones 130 is placed in the container11, the packer places a divider or spacer member 131 therebetween. Thespacer members 131 function to hold the spools 132 apart and form basesfor additional layers of cones 130 so that when the packer completes thepacking of the yarns, there are a plurality of layers of cones 130, oneabove the other, the cones 130 in each layer being disposed inside-by-side relationship. For this purpose, the spacer members 131 areprovided with alternate, relatively large holes for receiving the bottomend of spools 132 and relatively small holes for receiving the upperends of spools 132. Thus, the spools 132 are staggered with respect toeach other in a vertical direction.

It will be understood by those skilled in the art that the dimensions ofcontainer 11 are such that the topmost layer of cones 130 will projectslightly above the upper edge of panels 21, 22, 23 and 24. Thus, aportion of the uppermost layer projects outwardly beyond the score lines40, 41, 42 and 43. Therefore, if the container 11 is to be closed, thecones 130 must be compressed within the container 11. Normally, thecompression is for a distance of approximately 2 inches and is for thepurpose of urging the ends of the spools 132 tightly into seatedpositions in the spacer members 131.

After the cones 130 have been packed in the container 11, the door 50 isclosed so as to be coplanar with the remaining portion of panel 22. Thetop flaps 59 and 69 are folded, along top flap score lines 55 and 65,over the top of the top layer of cones 130, the fiaps 59 and 69 beingfolded inwardly toward each other so that their edges 56 and 66 abut.Then, a tape is passed over the abutting portions of the flaps 59 and 69so as to retain them together. It will be understood that, in manyinstances the fiaps 59 and 69 are not, and need not be, long enough tohave their edges 56 and 66 abut.. In such instances, the flaps 59 and 69need not be secured together or to anything. Thereafter, the flaps 79and 89 are folded along top flap score lines 75 and 85, over the flaps59 and 69 and likewise held in a closed condition with their edges 76and 86 abutting relationship by means of a tape 133. If desired, theflaps 59 and 69 may be glued or strapped to the flaps 79 and 89 to formthe close-d top of the container 11.

The tape 133 may, if desired, be commenced at score line 40 and extendalong the central portions of intermediate flaps 57 and 58 and thenceacross the edges of flaps 79 and 89 and then along the central portionsof flaps 68 and 67 to terminate at score line 41, thereby securing theflap members 29, 31, 33 and 35 in relative positions for compression. Bysuch an arrangement the container 11 when closed will tend to lock theend portions of the tape 133 between the inner intermediate flaps 57, 67and their associated panels 20 and 21.

It will be understood that when the top flaps are closed to form a top,as aforesaid, the intermediate flaps are essentially in their uprightextended positions so that the top formed by the top flaps 59, 69, 79and 89 is spaced from the upper edges of the panels namely edges 40, 41,42 and 43. The width of two of the intermediate flaps such as flaps 77and 78 is greater than the height above the edges 40, 41, 42 and 43 thatthe cones 130 extend. Therefore, no compressive force need be exerted bythe closing of the top. The container 11 is now essentially in thecondition illustrated in FIG. 6.

Next, the container 11 with its top closed is fed beneath the rammechanism shown in FIG. 2. The fingers 101 of the ram mechanism extendessentially outwardly as the top of container 11 is positioned beneaththe platen 92. Thereafter, the cylinder 91 is actuated to extend thepiston 90 and hence bring the platen 92 down upon the top of thecontainer 11. This urges the closed top formed by the flaps 59, 69, 79and 89 downwardly flat on top of all cones 130 in the uppermost layer.As the top is moved downwardly, it causes the intermediate flaps to jackknife outwardly and be progressively closed toward each other, pivotingabout the scorelines 54, 64, 74 and 84 and also pivoting about thescorelines or edges 40, 41, 42 and 43, as well as pivoting about thescorelines 55, 65, 7 5 and 85.

Thereafter, the piston 90 moves downwardly a distance sufficient to seatthe container top on the edges 40, 41, 42 and 43, as illustrated inFIGS. 3 and 7. At this time, the inner and outer intermediate flaps ofeach panel, such as flaps 77 and 73, are brought flat against each otherand extend essentially outwardly in a horizontal position. Next, sincethe actuator 130 has engaged the switch 121, during the last incrementof the downward movement of the piston 90, the cylinder 113 is actuatedto extend the piston rod 114 and thereby pivot all fingers 101simultaneously downwardly to vertical positions. The fingers acting uponthe outer intermediate flaps 58, 63, 78 and 88 simultaneously, urgethese intermediate flaps from the position shown in FIGS. 3 and 7 to thepositions shown in FIGS. 4 and 8.

The fingers 101 in their vertical positions, as illustrated in FIGS. 4and 8, hold the intermediate flaps fiat against their associated panelsand the operator passes a metal strap 134 around the lower portion ofall fingers, drawing the strap 134 tight in position covering the midportion of all outer intermediate flaps 58, 68, 78 and 88. The fingers101 are then withdrawn by the retraction of piston rod 90 therebysliding from beneath strap 134 and leaving the container 11 in a closedcompressed condition as illustrated in FIG. 10.

When the piston rod 90 approaches its uppermost position, the actuator120 engages the switch 123 which, in turn, actuates the cylinder 113 toretract the piston rod 114 and thereby tilt the fingers 101 to theiressentially horizontal or outwardly extending positions. The rammechanism, therefore, is in a position to receive the next container 11to be compressed and sealed.

It will be recognized by those skilled in the art that While the presentcontainer 11 is particularly useful for forming a compressed package oftextile yarns, the container 11 has other and varied uses in that acontainer of one length, ie a relatively long container may be producedby simply leaving the intermediate flaps 57, 67, 77, 87, 58, 68, 78 and88 extended in the plane of their respective panels and forming a top byfolding the top flaps 59, 69, 79 and 89 inwardly. Also, a relativelyshort container may be formed by folding the intermediate flaps 57, 67,77, 87, 58, 68, 78 and 88 against the outer surfaces of panels 26, 21,22 and 23 as illustrated in FIG. 10.

Furthermore, the inventive concept is not limited to fibre boardcontainers, such as the illustrated container 11, or to the applicationof force or pressure in a specific direction since it will be understoodthat other containers having laterally deformable flexible portions mayreadily be compressed utilizing the teaching herein, the flexibleportions being held in various Ways after compression so as to retainthe compressible material therein in a compressed condition.

It will be obvious to those skilled in the art that many variations maybe made in the embodiments here chosen for the purpose of illustratingthe present invention without parting from the scope thereof as definedby the appended claim.
